“…CEA is a fast and accurate combustion code, which is usually used to analyze and validate combustion processes (Chen et al 2012). Minimization of free energy approach to chemical equilibrium calculations has been used in all versions of this program (McBride and Gordon 1996). In this analysis module chemical equilibrium analysis was performed for modeling adiabatic combustion.…”

Space propulsion systems play an increasingly important role in planning of space missions. The traditional method for design of space propulsion systems includes numerous design loops, which does not guarantee to reach the best optimal solution. Multidisciplinary Design Optimization (MDO) is an approach for the design of complex systems that considers a design environment with multiple disciplines. The aims of this study are to implement and compare Multidisciplinary Feasible and Collaborative Optimization architectures for the multi-Objective optimization of a bipropellant space propulsion system design. Several disciplines such as thrust chamber, cooling, and structure were exploited in a proper combination. The main optimization objectives in the MDO frameworks were to minimize the total wet mass and maximize the total impulse by considering several constraints. Furthermore, Genetic Algorithm and Sequential Quadratic Programming are employed as the system-level and local-level optimizers. The presented design methodology provides an interesting decision making approach to select the best system parameters of space propulsion systems under conflicting goals.

The design of space systems is a complex and multidisciplinary process. In this study, two deterministic and nondeterministic approaches are applied to the system design optimization of a spacecraft which is actually a small satellite in low Earth orbit with remote sensing mission. These approaches were then evaluated and compared. Different disciplines such as mission analysis, payload, electrical power supply, mass model, and launch manifest were properly combined for further use. Furthermore, genetic algorithm and sequential quadratic programming were employed as the system-level and local-level optimizers. The main optimization objective of this study is to minimize the resolution of the satellite imaging payload while there are several constraints. A probabilistic analysis was performed to compare the results of the deterministic and nondeterministic approaches. Analysis of the results showed that the deterministic approaches may lead to an unreliable design (because of leaving little or no room for uncertainties), while using the reliability-based multidisciplinary design optimization architecture, all probabilistic constraints were satisfied.

“…In order to attain the goal, various Multi-Disciplinary Optimization (MDO) methods associated with the multidisciplinary engineering is utilized since the space launch vehicle is the multidisciplinary engineering system whose interconnected subsystems belong to different physical domains. 6 Based on the aforesaid, our mission design process was established to aim for suggesting the system baseline and mission profile with respect to requirements through revolutionarily rational methods. As part of the aforesaid, the database for the world competitive rocket systems was constructed.…”

In this study, a mission design process for space launch vehicles was established based on the systems engineering process and implemented to obtain the system baseline and the mission profiles. The process was sophisticatedly developed for users to make necessary decisions and to obtain design results rapidly. Database for the world's competitive rocket systems was built for the use of data mining. Seven disciplinary modules, such as the Weight Estimation, Mission Velocity, Staging, Propulsion, Configuration, Aerodynamics, and Trajectory, were developed for low fidelity analysis, and integrated as a system level process. In addition, several data mining techniques were adapted to the process as an alternative method of the requirements analysis, and utilized to provide the initial values of design parameters. Based on the established process, a design was optimized, and it was successfully converged. Through the multidisciplinary design optimization, it was possible to obtain the system baseline and the trajectory.
